Zusammenfassung:	PROBLEM TO BE SOLVED: To keep precision of a cylinder inner peripheral surface, functioning as a bearing surface, excellent without using a receiving tool such as a mandrel when the bearing member is inserted into a fitting hole and fitted by crimping.SOLUTION: A bearing member 42 includes a thin cylinder part 48 provided with a second cylinder outer peripheral surface 54 and a second cylinder inner peripheral surface 56 having a larger diameter than the first cylinder inner peripheral surface 52 in addition to a large-diameter cylinder part 44 and a small-diameter cylinder part 46 having a first cylinder inner peripheral surface 52 functioning as a bearing surface, and is fitted integrally cramping a peripheral edge of a fitting hole 34h by crimping the thin cylinder part 48 in an axial direction. In this case, even if the second cylinder inner peripheral surface 56 of the thin cylinder part 48 swells toward an inner peripheral side owing to the crimping, there is not a risk of influence on bearing performance as long as the diameter is not smaller than that of the first cylinder inner peripheral surface 52 functioning as the bearing surface, thereby keeping the precision of the first cylinder inner peripheral surface 52 excellent without using a receiving tool such as a mandrel.
